Filed: 1937-10-16
Abstract: 503,872. Flow - meters for liquids ; ratchet gearing. SERCK, H. O. Oct. 16, 1937, No. 28232. [Class 102 (i)] [Also in Group XXIV] A flow-meter for fuel or other liquid comprises a pump having a variable displacement, means to vary the said displacement in accordance with the pressure of liquid in the discharge line, and means to indicate and/or record the amount of liquid pumped. Fig. 1 shows a single piston 1 which is reciprocated from an eccentric 3 by a lever 2 having a fulcrum 4 which is movable by a spring-loaded control piston 6 sliding in a cylinder 6 under the action of the pressure of the liquid delivered by the pump against the action of a spring 6a. The reciprocatory movement of the piston 1 is converted into uni-directional rotation of an indicating hand 12 by means of a rack 7, a quadrant 8, friction and retaining pawls 9, 10 and a wheel 11. The momentary consumption may be measured by means of a Venturi instrument in the discharge line beyond the piston 5. Fig. 2 shows two pistons 15, 16 reciprocated within cylinders 13, 14 by a fixed-fulcrum lever 25, the crank-arm of which has its pin 24 slidably engaged in a slot in a reciprocating member 17 pivoted about a fulcrum pin 18 journalled in a spring-loaded bell-shaped control piston 19, liquid being dis. tributed to the cylinders by a rotary slide valve 21. Movement of the bell 19 may operate a pointer over a scale to indicate the flow of liquid per unit of time. The bell-shaped piston 19 may be replaced by a metal bellows. The alternate reciprocatory movements of the pistons 15, 16 may be converted into unidirectional rotation of a spindle 30, Fig. 6, carrying a counter, by connecting their upper ends with the free ends 35, 36 of two steel or inextensible ribbons 26, 27 passing round rollers 28, 29 on the spindle 30 and interconnected by a wire 33 passing round a roller 34, a spring 37 serving to maintain the ribbons taut. The counter may be combined with speedometer or dynamometer mechanism so as to indicate consumption per mile or per horsepower, and the indicating means may be combined with moving charts and styles for giving permanent records.

Patent GB-387765-A (GB)
Title: The manufacture of acid wool dyestuffs of the anthraquinone series
IPC: C09B1/24
Filed: 1931-10-13
Abstract: Aminoanthraquinone derivatives are prepared by replacing in either sequence one halogen atom of a 1,4-diamino-2,3-dihalogenanthraquinone by a mercapto or disulphide group by means of an alkali metal sulphide followed by oxidation of this mercapto or disulphide group to a sulphonic acid group, and replacing the other halogen atom by an aryloxy group by treatment with a phenol.  The resulting products, 1,4-diamino - 2 - aryloxyanthraquinone-3-sulphonic acids are similar to but purer than the products of Specification 363,027 and they may be further sulphonated.  The oxidation of the mercapto or disulphide group is effected in acid or alkaline medium by means of hydrogen peroxide or alkali metal peroxide, perborate or persulphate.  The introduction of the aryloxy group is effected by heating in presence of an acid-binding agent and advantageously at about 100 DEG  C.  In examples, (1) 1,4-diamino-2,3-dichloranthraquinone is boiled with excess sodium disulphide to give 1,4-diamino-3-chloro-2-mercaptoanthraquinone, this is oxidized by hydrogen peroxide to the corresponding 2-sulphonic acid, and the latter boiled with phenol in presence of sodium carbonate; sulphonation of this dyestuff by means of concentrated sulphuric acid gives a soluble, blue wool dye; (2) 1,4-diamino-2,3-dichloranthraquinone is heated with sodium phenolate in phenol to give 1,4-diamino-3-phenoxy-2-chloranthraquinone; treatment of this with excess sodiumdisulphide in alcohol replaces the 2-chloro atom by a mercapto residue, which product is oxidized by hydrogen peroxide (or alkali peroxides or perborates) to the 2-sulpho derivative; (3) 1,4-diamino-3-chloro - 2 - mercaptoanthraquinone (cf. 1) is oxidized to the 2-sulpho derivative by means of concentrated sulphuric acid and potassium persulphate, or the starting material is first converted to its zinc salt or the disulphide by zinc chloride and air oxidation respectively, and p  then oxidized; a 1,4-diamino-3-bromo-2-sulphoanthraquinone is similarly prepared from 1,4-diamino-2,3-dibromanthraquinone, and both products on heating with p-cresol yield an acid wool dye (navy-blue); (4) if phenol is replaced in (1) by resorcinol a blueish-violet acid wool dye is obtained and similar shades are also obtained by using guaiacol, m-hydroxybenzoic acid, or xylenols; (5) 1,4-diamino-3-chloranthraquinone - 2 - sulphonic acid (cf. 1) is heated with an alkaline solution of a - or b -naphthol; a navy-blue acid wool dye is obtained; (6) 1,4-diamino-3-b -naphthoxyanthraquinone-2-mercaptan (prepared in an analogous manner to the phenoxy derivative--cf. 2) is oxidized with hydrogen peroxide to give the same product as in (5).  The products are dyes for acetate silk as well as wool.
